G-spot and pain?

I'm 25 and I honestly don't know if I had ever had my g-spot stimulated before tonight. I ordered a g-spot vibe from here, The Pretty Pearl G-spot and got it out tonight. I had my partner use is on me to help me find it. He was able to but afterwards I now have cramps and it's just feeling....weird?
Everything talks about the gspot this or g-spot that and it's amazing but is it possible that it isn't true for all women? I honestly prefer clitoral stimulation or just normal sex. I can't help but feeling odd or like something is wrong with me He was gentle with me and not doing it hard or rough at all. It was just uncomfortable for me.....
Does anyone else have this problem?

I can't be certain about the cramps, since I've never heard of G-spotting giving anyone those, but you're not abnormal for not liking G-spot stimulation. While many ladies adore G-spot stim, there are some who don't care for it or even outright hate it, and there's nothing wrong with that. Though I'd say maybe try one or two more G-spot toys just to see if it's perhaps the shape or vibrations that bugged you.
